voltage question

[foghorn]

I am getting ready to build myself a rc boat to pull my lines out below the dam to where i cant cast to. My question is how much voltage will the reciver handle as i was thinking of using a small motorcycle battery to power it from. I will either be using one or two 1/4 size servo's or bigger to turn this with as it will have a 28lb thrust trolling motor for power. I seen a guy using a boat like this and his servo wasnt powerful enough to turn it when the trolling motor was running. I did ask him what size servo he was using but he didnt know or wouldnt tell lol.

Depends on the receiver. Some of the newer 2.4ghz will handle 7.4v or even 11v volts, but most of the older ones have a 6 v limit. But you can run a regulator between the battery and receiver, from what I gather it has to be able to run the amperage for the servos and be switchable. I'm not sure what is switchable , I am guessing the polarity.

You are talking ground frequencies, which I am unfamiliar with, I only can say for sure with airborne receivers. It may pay to search the receiver brands website, it may say what the limit is.

Well it dont matter if its ground freq or not to me. I always thought they all ran on a set band width as far as freq's. But of course i was thinking of using just a 2-3 ch radio as all i need is steering and power on/off for the motor.

I just meant that ground frequency gear may allow higher voltage, which I couldn't say one way or other. I suspect not. When there was a lot of interference in the FM bands they separated ground form air. Air frequencies are 72mhz and now 2.4 ghz, and ground is 27 and 75mhz, they run both at 2.4 as well now since they automatically channel hop.


If you were running standard electric RC boat, the receiver will be regulated through the ESC.

I don't know if it could be adapted, I imagine it could be since you can run up to 6 or even 12 cell lipo batteries on some of them which is 44v and they go up to 180 amps. But 12v may not be enough even, and you may have to bypass the electronic speed control on the motor itself.

This is definitely not my field of experience by any means, I still believe they fill motors with magic smoke, and once it gets out they don't work anymore.
